A sticker on a mirror. That's the whole idea.
In 2019, Lorraine producer Helen Addis put a simple reminder in changing rooms across the UK: while you're getting changed, check your breasts. Seven years on, that sticker has travelled from shop mirrors to the back of Royal Mail post, into Parliament, and onto studio doors where it caught the eye of Davina McCall.
Founded by Helen Addis MBE · Launched on ITV's Lorraine, 30 April 2019
The Change + Check sticker, now in thousands of changing rooms nationwide.
Over 55,000 women are diagnosed with breast cancer in the UK every year. The earlier it's found, the better the odds. Change + Check puts the prompt exactly where people are already undressed and in front of a mirror.
Helen Addis, a producer on Lorraine and mum of three, is diagnosed with grade 3 breast cancer at 39, after a segment on the show prompts her to check. She documents her treatment through her blog, The Titty Gritty.
Change + Check launches on Lorraine. Reminder stickers go up on changing-room mirrors at John Lewis, David Lloyd Clubs, Monsoon and ASDA.
The Metropolitan Police joins the campaign. Madonna and Naomi Campbell lend their support. The campaign is raised at Prime Minister's Questions, and Theresa May writes in praise of it.
Royal Mail franks the nation's post with the Change + Check message, bringing the reminder to doorsteps during the pandemic, when routine screening had fallen behind. The Boob Bus tours the UK each October.
In its seventh year, the campaign launches National Check Your Boobs Day, an annual event on 1 October, with Boots among the supporters putting the prompt in front of shoppers.
Davina McCall reveals that Change + Check signs on studio doors prompted her to get a lump checked. It was breast cancer, caught early. She becomes one of more than 150 people who credit the campaign with finding theirs.
"Lorraine had put signs on the back of all the doors saying 'check your breasts'. And every time I went for a wee, I did that, and it was still there."

Davina found her lump while filming The Masked Singer, where Change + Check signs had been placed on the studio doors. The cancer was very small, caught very early, and removed with clear margins. As Lorraine Kelly put it: "That's the whole point of the campaign — to raise awareness and save lives."
The campaign works because organisations give it wall space where it counts.

Get to know your normal. Check regularly — in the shower, getting changed, wherever the mirror finds you. If anything changes, see your GP. That's it. That's the campaign.
